PUZZLE.

SPECIFICATION forming part of Letters Patent No. 474,627, dated May 10,1892. Application filed March 5, 1892. Serial No. 423,811, (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. BURNETT, a citizen of the United States,residing at Danbury, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inPuzzles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has for its object to produce a simple and inexpensivepuzzle which shall require a steady hand and considerable skill tooperate and shall be sufficiently attractive to entertain both childrenand adults.

With these ends in viewI have devised the the novel puzzle which I willnow describe, referring by numbers to the accompanying drawings, formingpart of this specification, in which- Figure 1 is an elevation of mynovel puzzle, the parts being at the starting position; and Fig. 2 is asectional view corresponding therewith.

My novel puzzle consists, essentially, of a base 1, astandard 2, made,preferably, in a single piece, as shown in the drawings, a disk 3,having a peripheral groove 4, a stop 5 in the groove, and a ball 6. Thepuzzle is to change the ball from one side of the stop to the other bysimply rotating the disk. The disk is centrally pivotedupon a pin 7,which is adapted to engage either of anumber of holes Sin the standard.These holes are in planes oblique to the plane of the standard, it beingapparent that the more nearly horizontal the pin is to the plane of thebase the more nearly vertical will be the plane of the disk, andconsequently the greater the liability the ball to roll off and thegreater the difficulty of solving the puzzle. The disk is provided witha pivoted hand-piece 9 for convenience in manipulation and ordinarilywith a depression 10 on the finishing side of the stop, in which theball lodges when the puzzle is solved.

The operation is as follows: The ball is placed at the highest point inthe groove on the opposite side of the stop from the depression, asshown in the drawings. The disk is then moved slightly toward therightthat is, in the opposite direction from the arrowto start the ballrolling, and is then rotated toward the left, as indicated by the arrow.The ball must not be allowed to roll 0%, but the disk must be socarefully manipulated as to keep the ball nearly at the top of thegroove, but rolling toward the left, until the disk has been given anentire rotation, when the ball will lie in the socket on the oppositeside of the stop, as indicated by dotted lines in Fig. 1.

It will of course be apparent that the details of construction may begreatly varied without departing from the principle of my invention.

I claim- 1. A puzzle consisting, essentially, of a standard, a pinextendingobliquely therefrom, a disk pivoted on said pin and having agroove in its edge and a stop, and a ball lying in said groove andadapted to be passed from one side of the stop to the other by rotationof the disk.

2. A puzzle consisting of a standard having oblique holes near its top,either of which is adapted to receive a pin, a disk pivoted on said pinand having in its edge a groove, a stop in said groove and on one sideof said stop a depression, and a ball adapted to be placed on theopposite side of the stop from the depression and to be moved into thedepression by rotation of the disk.

3. A puzzle consisting of a base, a standard having oblique holes, a pinadapted to engage either of said holes, a disk pivoted on said pin andhaving in its periphery a groove, a stop in said groove, a pivotedhand-piece by which the disk is rotated, and a ball lyingin the grooveand adapted to pass from one side of the stop to the other.

In testimony whereof Iaffix my signature in presence of two witnesses.

WILLIAM H. BURNETT.
